Trivia:

The 2.2.5 version item description "Ducks quack" refers to the common pronunciation of "Duct" as "Duck". When duct tape was first created, it was used for waterproofing and called, "Duck Tape." Later, it was used to fix ventilation shafts gaining the now frequently used "Duct Tape." Now, Duck Tape is a brand of duct tape.
